a plication fll'ed April as,

To ll in ham it may concern Be it known that L'Hiqafitnrr NIGEL Gues- .LEY, a subjectof the King of Great Britain and Ireland, residing at Don'caster, England, (whose post-oflice address is Avenue House; Doncaster', in the county of York, En land,) have invented certain new and use ul Imioveme'nts in or Relating to Bailway and l mmws j Vehi'clesg'and I do here by declare'the f0 lowing to be a full, clear, and exact descriptionof the invention, sri'ch' as will enableothers skilled in the art to which: itappei'tiiins to make and use the same. p

This invention liasrefel 'ence to rail way and tramway vehicles of the kind in which the adjacentends of two veliicles are supported by one common bogle, the other end of either or each of thesaid vehicles being supported on an independent bogiegor on another bogie which also supports one end of another vehicle.

In an arrangement of this kind described in the specification of my prior British Let-' ters Patent No. 4512 of 1907 the two vehicles are supported on and articulated to their common supporting bogie through brackets fixed to the vehicle ends and so formed as to engage one with the other and thereby serve as a coupling or connection between the vehicles. a

The object of the present invention is to provide an arrangement in which the two vehicles whilst supported on the common bogie by brackets fixed to the respective ends of the two vehicles are connected by draw gear comprising a, draw spring or springs so that in a train of vehicles the pull at starting is taken up vehicle by vehicle through the draw springs and gear ther by enabling the load to be advantageously taken up gradually at starting instead of the whole load being taken up at once as is the case where the su porting brackets also consti tute the coupiin means as described in the said prior speci cat-ion which do not pro ride for the movements necessary when draw springs are employed.

A further object of the invention is to provide an improved construction and arrangcnlent of supporting brackets elnlvnl in; lateral (o-acting bearing surfaces of consi lcrablc area for taking the weight of the vchi les and transmitting the same to tilt bugle means being provided for the ellirient I Specification of Letters Patent.

lubrication of such surfaces In this way it may be possible to dispense with side brackets fixed to the adjacent I two vehicles. and that either rest on bearin plates fixed to the spring porting British 190? or bear one upon the other as described in another specification Patent granted to me.

. bolster of the sup bogie HSdQSCIlbBd in the said prior vention, the adjacent ends of the two. ve

ends of the of British letters 1 i 65, v v For the said purposes, according toithejm 1 patent specification No. 4512 of-11' hicles connected together by-draw. gear comprising a draw spring or sprin 5 ported upon the common bogie or the l1ke fixed to the respective are saprackets vehicle ends and mutually engaging one another so i as to prevent relative movement in a lateral directlon whilstcapable not only of relative angular movement to allow for movement of the two vehicles about the axis of the oentre casting or swivel plate of the common boqic but also capable of relative lbngitudh nu movement to allow for mo'venients'due to compression of the draw springs.

One embodiment of such an arrangement comprises a bracket or the like fixed to one vehicle end and adapted to rest on the bogiecentre casting or swivel plate-finial formed with an upwardly extending par -cylindhical boss or part-annular flange em raceduby t P M ng parts of another bra ket or the like fixed to the end of the other: ve-

hicle and resting upon the first mentioned bracket or the like, the. arrangement being such that the two brackrts rah tui'n relatively to each other about the axi of the bogic centricasting or sw 'wlql plate a well as move longitudinally tfiiively to each other to provide for compression of the draw springs A coupling pin carried by the illiltlfli, or the like lived {uone vehicle engages al: eve on the ln-rnl vi a draw her carried by the other vchichand associated with a draw spring or springs. The. coupling pin ma extend ccnilullv through the bogie centre casting or swivel plate and constitute the kins bolt or pivot of the hogie.

To limit the relative angular movements of ill: tu' vchw-lcs about the axis of the bugle centre rust in; or so ivcl plate security lllilliiS may r nwct the adjacent headstocks of th fun vcliu lesncar the sides of the who l7 'esnul side huli' rs may be fitted s6 other is compressed when the re are travelling on curved portions of that. oneor hicles track.

Fig. l of the accompanying illustrative drawings shows in side elevation the ad jacent ends of two railway passenger vehicles support-ed upona common bogie, by means embodying the invention.

Fig. 2 shows in side elevation, to a larger scale, the supporting and coupling arrangement,

Fig. 3 is a central vertical longitudinal section on the line A, A of Fig. 4, of the sup porting and coupling arrangement.

Fig. 4 shows the supporting and coupling arrangement in plan,- and Fig. 5 is a transverse'section. corresponding to the line B, B of ig. 4. I

1 and Q indicate the ends of the two ve hicles, 3 the bogie, supporting the same through the spring bolster 4, and 5, 6, the brackets fixed by bolts 7 to the headstocks H of the vehicle underfra'mes 9.

The bracket 5 has a horizontal base 5" which "rests directly upon the centre casting or swivel plate 10 ofthe bolster 4, and which is formedv with an annular downwardly extending projection 11 that engages a corrcsponding annular recess formed in the bolster centre casting or swivel plate 10. Curved upwardly projecting flanges or webs 12 that connect the vertical wall. of the bracket 5 to the base 5 thereof, form a part cylindrical boss the axis of which is in line with the axis of the bogie centre casting or swivel plate lU,"and these curved flanges or webs are embraced by corresponding curved flanges or webs 13 connecting the horizontal base portions 6" of the bracket 6 to the vertical wall of such bracket. The curvature of the flanges or webs 13 does not extend beyond the point of greatest diameter of the curved flanges or webs 12 so that whilst these mutually engaging flanges or webs 12 and hicle ends to which the brackets are fixed. they do not prevent relative longitudinal movement of the brackets when the one vehicle is pulled away from the dther as in the compression of the draw spring hereinafter referred to, neither do they prevent free relative angular movement of the brackets about the axis of the bogie centre casting or swivel plate. The horizontal base'portions 6 of the bracket 6 rest and work on the laterally extended side portions of the base 5 of the bracket 5 and to reduce friction the upper faces of said side portions have formed in them grooves 14 to which lubricant is supplied through grease cups l5 screwed into the horizontal base portions ll of the brackets (I.

Projecting from the bracket is a orkcd vertical wall of the boss 16 the liorizontallv extending ja oi" holes to IP.('Ll'\ a oupling pin 17 the axis of which is in line with the axis of the centre casting or swivel plate 10 of the bolster 4. he jaws of the forked bos l6 embrace the head 18 of a draw bar 19 which extends through the bracket 6 and the headstock 8 of the corresponding vehicle 9, a draw spring india rubber ring type, being mounted on the draw bar 19 between the back of the head stock 8 and a bearing washer 21 which is backed by a nut 22 on the inner end ofthe draw rod. The coupling pin 17 passes through a hole formed therefor in the head 18 of the draw bar 19, and, as will be seen, the forked boss 16, coupling pin 17, and draw bar head 18 are located centrally within the which are formed with "0, preferably of the welLknown concentric a part annular wall formed by the flanges or posed between the head flange 18 and the bracket 6.

In the apparatus illustrated the coupling pin 17 is formed with a downwardexterr sion 1? that constitutes the king bolt or pivot of the bogie and engages holes formed therefor in the base 5 of the bracket 5 and in the centre casting or swivel plate of the bogie bolster 4.

It will be seen that the (to-acting surfaces of the webs or flanges l2 and 13 of the brackets 51 and 6 prevent rclati ve lateral movement of the adjacent ends of the vehicles. whilst ment about the coupling pin and king bolt 17, 17*, as also free. relative longitudinal movement when the draw spring 20 is compressed. The. a rcuate guides 12 and 13 permit the draw bar 19 to slide longitudinally and C(HHPIESS the spring 20, and the Sprihgs 20 in a train of cars relieve the engine of great strain in starting. which is found to be very advantageous.

Supporting and con pling means as hereiubefore described may va ry considerably in details of construction as will be understood allowing free angular move-' e head tive to the otherear and which prevent relative lateral movement between the ears, and a spring-controlled draw bar slidable in one of the said brackets and pivoted to the other bracket concentric with the said arcoate guides.

2. The combination, with the adjacent end portions of two cars, and a supporting carri arranged under them and provided wit a bolster; of brackets secured to the ends of the cars and provided with ai'cuate guides which permit one car to move longitudinally and pivotally relative to the other car and which prevent lateral movement bctween the cars, means which connect one bracket pivotal] with the said bolster, and a spring-control ed draw bar pivoted to the last said bracket concentric with the said arcuate guides, said draw bar being slidable longitudinally in the other bracket.

3. The combination, with the adjacent end portions of two cars, and a supporting carriage arranged under them; of brackets securedto the ends'of the cars and provided with arcuate guides the contacting part. of which are portions of vertically arrangedcylinders. said guides operating to prevent one car from moving laterally of the other car and to permit one car to move longitudinally and pivot-ally relative to the other car. and a spring-c1mtrolled draw bar slidable in one of the said brackets and pivoted to the other bracket concentric with the said arcuate guides.

4. The combination. with the devices as set forth in claim 1. of horizontally arranged base portions on the said brackets. said base portions beinp, arranged to overlap and bear on each other. and the lower base portion being arranged to bear on the upper part of the supporting carriage.

In testimony whereof l aliix my signature, in presence of two witnesses.
